To al whom it may concern:

Be it known that I, EMIL KRAMER, a citizen of theUnited States,-residing at Pax ton, in the county of Ford and State of Illinois, have invented a new and useful Harrow Attachment for Plows, of which the followingis a specification.

This invention has relation to harrow attachments for plows and it consists in the 'novel construction and arrangement'of Its parts as hereinafter shown and described. The object of'the invention is to provide a plow attachment having rotary members adapted to engagethe soil at the time'that it Is turned and pulverize the same beforeit has had'sufficient time 'to harden and formv into clods;

Theattachment consists primarily of a frame-adapted to be'applied to the frame of a plowand which is provided with means for ateral adjustment with relation to the plow and pivot joints whereby the majorportion of the attachment and the ground engaging elements thereof may be pi'tched' at-any desired angle with relation to the line of draft.

The ground engaging elements are carried by a spring actuated. arm, the tension of the spring of which holds the said element in contact with the ground, said arm bein adapted to swing vertically. A lever mec anism is rovided for swinging the arm and ma also e -manipulated to increase or. diminis the I tension of the spring as desired. F In the accompanying drawings :Fi ure 1 2, is a side elevation of the same. Fig. 3 a,

erspective view of a modified form of barv or. carrying the earth engaging elements. Fig. 4 is anedge elevation of one form of earth engaging elements having a series of- .actini'ally disposed blades. Fig. is a .side

elevation of the same, With'PflItS removed. erspective view .of amodified form of start ard used upon the attachment; and Fi 7 is a side elevationof s'till another formo standard. a The attachment consistsbf the bracket 1 which is provided at one-end'wit'h a circular ortion 2 havin a ridgedunderfacetl The ame 3 of the 'ow is provided with a corre spondin circ ar' rtlcm 4. The'portions 2 and 4 ho ted toget er-but may be axially adjusted with relation to each other. The block 5 may slide longitudinally along the bracket 1 and may be secured by set screws at'any desired point thereon-. Thesaid-zbloek isrprm vided with a circularroughenedportion- 6 whichyisadapted to be eiigaged by acorns-- spondingportionW. The said parts 6 and 7 {are bolted together and may be-axially adjusted with relation to. each other. The

part 7 isprovided with abearing. 8 and oneendof the arm- 9 is -j ournaled in the=said-bear-'- ing.- The standard 10 is mounted upon the" bearing 8- and is provided at its upper ='-endwith-a-gear segment 11. 1 The lever '12 isconcentrically fulcrumed with'relation to the segment 11 and is provided -with'a spring actuated awl 13 which engagesthe ratchet tli The gear wheel teeth of c said segment. 14 is concentrically mounted upon the fulcrum of the lever 12 and meshes with the ,teeth of a bar 15. Said bar passes under a ratenteamarch'io,1908i" guide 16 attached to, the side of astandard 10.

The lower end of the said: bar passes through a. clip 17 attached to the arm 9. and

the coil spring 18 is interposed between the said 'plateand the pin 19 carried by the said bar-15; The clip 20 is adjustablyattac'hed to the lower portion of the=arm 9 and is pro-- vided with a circular rou hened portion 21.

' The circular roughened lock 22 is mounted upon the bar 23 and engages the roughened portion 21. 22 may be turned axially with relation to each other. As shown in Figs. 1 and 2, the bar 23 may bestraight. modified form of the said bar in which form the bar is made up of aseries of zigza sections, the objectof which-arrangement be hereinafter explained. The standards24 depend from the bar 23 and the earth engaging elements12f5 are journaled at the lower ends of the said standards. The said elements 25 may be in the form of/disks, as shown in Figs. 1 and 2, or in the form of radial blades as shown in Figs. 4

' and 5.. In either instance the ground en agingelements are pitchedat an angle to the surface of the ground as illustrated in Fig. 1.

.When the disks 25 are used the scrapers'26 are attached to'the next adjacent standard 24 to that carrying the disk upon which they operate. 1 The said'scrapers are adjustably mounted in the eyes 27. The blades 28, shown in Figs.4 and 5, are curved laterally, such curvature, however, -may be toward elements are not alined with each other transversely with' relation to the line of Fig. 3 shows a The said portions 21 and either side as desired. When the bar 23, as

\ draft but are located slightly in advance of each other in order to more effectually operate upon the loose soil.

From the foregoing description-t is obvi-,

thesam'e is provided with the parallel spaced bracket,

lower side portions between which the bear- .ing for the disk 25 may be adjustably secured while the up er portion of the'standard is provided with a means for clamping upon the bar 23. Thus making it possible to adar 23 and thereby increase or diminish the space between the same as desired.

In the form of standardlshown in Fig. 7 the standard may be adjusted upon the bar 23 and is then secured; in place-by means of a set screw.

Having described my invention what I claim asnew. and desire to secure by Letters- Patentis:+,,; v

'1. A plow attachment; comprising a bracket, a part adjustable on said block and posed between the arm ust the standards 24 longitudinally of the a. block slidably" located on the ard attached to the said part, a leverfulcrumed on the standard, a gear wheel attached to the lever, a gear rod meshmg wlth said gear wheel and slidably connecting with the arm and a coil spring interposed between the gear rod and the arm.

2. A plow attachment comprising a standard, a swinging arm, a lever fulcrumed to the standard, a gear wheel attached to said lever, a gear bar meshing with said gear wheel and slidably engaging said arm, a spring interand the gear bar, a zigzag bar attached to said arm, and ground engaging elements carried by the last said 3. A plow attachment comprising a stand ard, a swinging arm, a lever fulcrumed to the standard, a gear wheel attached to said lever, a gear bar meshing with said gear wheel and slidably engaging terposed between said gear bar and said arm, a collar adjustably carried by said arm, a bar adjustably attached to said collar, and earth en aging elements carried by said bar.

11 testimony my own, I have in the presence that I claim the foregoing as hereto affixed my signature of two witnesses,

EMIL KRAMER.
